WINDING-MACHINE.

To all whom it may concern:

Be it known that I, HERBERT E. SMITH, a citizen of the United States,residing at Manchester, county of Hillsboro, State of New Hampshire,have invented an Improvement in WindingMachines, of which the followingdescription, in connection with theaccompanying drawing, is aspecification, like characters on the drawing representing like parts,

This invention relates to winding machines for winding cloth into boltsand to similar machines and, has for an object to provide a safetydevice which will prevent the accidental rotation of the pivoted stiff--ening blade and in the preferred form the starting of the machine ofthis class when the heads and blade are not in proper adjusted positionwhereby the free end of the blade will be supported during'rotation,

Accidental starting of a machine of this class is particularly dangerousbecause when the machine is stopped and the bolt of cloth removed thestiffening blade is left free to swing about one end as a pivot. If theoperator accidentally moves the startinglever the blade swings as itrotates and causes serious damage to the machine and often seriousinjury to the operator. Another cause of accident is the carelessplacing of the cloth board in the machine in such a manner that the freeends of the board and blade are not properly clamped, In accord-- ancewith the preferred form'of my present invention I provide a simple andreliable device which prevents the shifting of the operatinglever tostart the machine when the parts are in any other position than that inwhich the ends of the cloth board and stiffening blade are properlyengaged and secured.

The novel features of the invention will be fully disclosed in thefollowing specification and accompanying drawings and particularlypointed out in the claims.

Referring to the drawings in which I have illustrated one embodimentofmy invention, Figure 1 isa back view of a winding machine showing myimproved safety device applied thereto, Fig. 2 is a front view of thesliding head and operating device therefor, Fig. 3 is an end view, andFig. 4 is a detail view of the heads and blade with a cloth board inposition.

Referring to the drawings in detail, 1 indicates a supporting frame, 2and 3 gear Specification of Letters Patent.

casings forming parts of said frame and 4 indicates a drive shaft. Uponthe drive shaft are mounted fast and loose pulleys 5 and 6 which aredriven by a belt 7. A belt shifter 8 pivotally mounted on the bracket 9secured to the frame is providedfor shifting the belt 7. 'A shaft 10,isrotatably mounted in the gear casing 2, and is con nectedto the driveshaft by suitable gearing. 'Pivotally mounted'upon the inner end of thisshaft is a head 11, to whichis secured a stiffening blade 12. This headis provided with a slotl8 adjacent the blade to receive a cloth board14:. slidably mounted in the gear case 3, is a shaft 15, to which isrigidly secured a head 16. and this head is slotted to receive the endbf the blade 12- lessthan the length of the lip 19. By this means whenthe shaft 15 with its head 16 is withdrawn the blade will rest againstthe lip 19 but may swing past the lip 18 to permit the removal of theboard 14 and the cloth wound thereon. Connected to the shaft 15 to movelongitudinally therewith but permitting free rotation of the shaft is aframe 20 which is V shaped and provided with the arms 21 and,22. Arod 23is connected tothe arm 21 and is slidably mounted .in brackets 24' and25 secured to the gear case 3 and on the end of this rod is a knob 26positioned to be within convenient reach of the operator. A spring 27positioned be tween a collar'28 secured to the rod and the bracket 25urges the rod inwardly and through the connections previously describedtends to move the head 16toward the head 11. A latch 29 is positioned toengage a slot 30 in the rod 28 and hold it in its outer position whenthe head 16 is withdrawn from the end of the blade 12. A springg3l urgesthe latch toward the rod and insures-its engagement in the slot 30 whenthe head is moved backto remove a bolt of cloth.

The mechanism so far described except for the shape of the frame 20 isof common and well known construction. I 5

In accordance with my present invention -I provide a safety devicewhereby it will be.

impossible to operate the belt shifter to" move the belt from the looseto the fast pulley when the head 16 is in its withdrawn position, orwhen this head has been moved forward and has failed to properly engagethe blade, thus avoiding accidents resulting from careless operation.

In the mechanism illustrated a rack 32 is connected to the belt shifteras by a link 33 and is provided with ratchet teeth 84:. A pawl 35 ispivoted to the gear case 3 and is urged toward the ratchet teeth 34 by aspring 36. The construction of the pawl and rack is preferably such thatthe shifting of swinging the pawl about its pivot to release ventstarting of the machine.

the rack 32. If however the cam moves beyond the normal position as itwill if the stiffening blade is not in position the pawl will bereleased to engage the rack and pre By this mechanism when the head 16is in position to properly engage the blade 12 the pawl 35 is held outof engagement with the ratchet teeth 34- and the belt may be shifted tothe fast pulley. If however the head 16 is withdrawn the cam 38 will beat the left of the projection 39 and the pawl 35 will engage the ratchetteeth 34: preventing the shifting of the belt to the fast pulley. If thelatch 29 has been raised to release the rod 23 and thereby the head 16and the head has moved forward under the influence of the spring 27 buthas not properly engaged the blade and the board mounted thereon theoperation of the belt shifter will still be prevented. For example, ifthe cloth board and the blade are not properly positioned as the head 16moves forward the end of the li 18 may engage the end of the board, or ithe blade is swung forward beyond the lip 18 the head will move too farforward. In either event the cam 38 will be at one side of theprojection 39 and will not hold the detent 35 in released position. aWhen the head 16 is in proper position holding the board and blade, thecam 38 will engage the projection 39 to hold the pawl away from the rackand the belt shifter will be free to be operated.

It will be clear to one skilled in the art that various modificationsmay be made without departing from the spirit of the invention asdefined in the claims. I

The essential feature of the invention is to provide a device which willprevent accidental rotation of the blade while it is free to swing aboutits pivotal support.
